3.  POSTURE OF TYRANNOSAURUS:  Vertebrates like humans that stand on two legs are referred to as "bipedal", while animals like cats that stand on four legs are referred to as "quadripedal". Is Tyrannosaurus bipedal or quadripedal? What about Allosaurus? Apart from foot structures, in what way is the posture of Tyrannosaurus and Allosaurus different than that of humans?

4.  FOOTPRINT OF TYRANNOSAURUS:  In the space below sketch the probable shape of a tyrannosaur footprint. Indicate the length of the footprint (from toe to heel). Are the footprints of Tyrannosaurus and Allosaurus similar in terms of shape? How could one distinguish between an allosaur and tyrannosaur footprint?

5.  TEETH, ARMS & HANDS OFTYRANNOSAURUS:Examine the teeth, arms, and hands of Tyrannosaurus. Are the teeth similar to one another in shape? Are they curved as in Allosaurus? Are the arms as large relative to the tyrannosaur body as the arms of Allosaurus relative to its body? How many fingers does Tyrannosaurus have? How many bones in a single finger? Is this the same as in Allosaurus?

You have now completed the formal part of the field trip. If you have the time and the inclination, there are still many course-related exhibits that you might want to see, particularly as they relate to subjects that will be discussed in the lecture part of the course later in the semester. A Field Trip Guide Appendix, which begins on page 6, is intended to help point you in the right direction if you decide you want to see more. The appendix-guided tour is not, however, a required part of the field trip, but you might find it useful for material covered later in the semester. And, it might actually turn out to be interesting.
